-
- Sqrt(x) returns the square root of x.

- On a VAX, sqrt(negative) returns the reserved operand and
- sets _e_r_r_n_o to EDOM .

- EERRRROORR ((dduuee ttoo RRoouunnddooffff eettcc..))
- Cbrt is accurate to within 0.7 _u_l_ps.
- Sqrt on a VAX is accurate to within 0.501 _u_l_ps.
- Sqrt on a machine that conforms to IEEE 754 is correctly
- rounded in accordance with the rounding mode in force; the
- error is less than half an _u_l_p in the default mode
- (round-to-nearest). An _u_l_p is one _Unit in the _Last _Place
- carried.
